To all whom it may concern:

Be it known that I, SEYMOUR W. PEREGRINE, a citizen oi the UnitedStates, residing at Portland, hhiine, have invented certain new anduseful Improvements in Carburetors, of which the following is aspecification.

My invention relates to carburetors and is designed to provide a simpleand effective construction having a maximum capacity and which. willproduce a uniform quality of the carbureted'fiuid.

The invention consists in the features and combination and arrangementofparts hereinafter described and particularly pointed out in the claims.

In the accompanying drawings,Figure 1 is a perspective view of theapparatus with interior parts shown in dotted lines. 2 is a crosssectional view with parts shown in elevation and showing a modifiedarrange ment of strainers or condensers in the dome. Fig. 3 a detailsectional view showing the manner of securing the textile strainers inplace. Fig. 4 is a detail view of the airinlet pipe and the pipe orchamber within which the air mingles with the oil. I

In these drawings, 1 indicates a tank of any suitable form, which in thepresent embodiment of my invention I show as of cylindrical shape,arranged in a horizontal position. This tank is adapted to contain abody of oil or gasolenc, which, in the normal operation of the apparatusreaches to the level of the line :cy. An air pipe 2 extends through oneend of the tank longitudinally of the same to about the center thereof,where it is turned downwardly, reaching to near the bottom of the tankand well below the oil level. At its lower end this air inlet pipe iscoupled to branches 3, 4, extending longitudinally near the bottom ofthe tank, the said branches being closed by a cap 5 at their ends, butberations directing the air current in different directions.

Surrounding the air pipe branches 3, 4, there is a pipe'or chamber 6 ofsufficient diameter to leave a space around the air pipe into which theair therefrom dis charges. The horizontal chamber or pipe 6 is coupledat its ends to vertical pipes or extensions 7 by means of the couplings8, the arrangement being such that the vertical pipes 7 extend above theoil. The chamber formed by the pipes 6 and 7 is closed against the inletof oil thereto excepting at the center of the pipe or charm her 6 wherean opening 9 is provided on each side of the said pipe or chamber ofsufficient size to admit the proper quantity of oil to be taken up bythe issuing from the perforations in the horizontal pipe sectionsE and4. i The area of these oil inlets to the pipe or chamher 6 as comparedwith the combined area of the air inlet perforations is such that aproper couuningling oi the airand oil will take place and a uniformquality of gaswill be produced by reason-oi this properly proportionedsupply of oil and air, it being understood that the air is admittedunder a constant pressure.

Above the oil level and at the top of the tank I suspend a series oflayers of burlap or other suitable textile fabric, each two sheets ofburlap being riveted as shown at 10, to strips of iron indicated at 11and these strips are then riveted as at 12 to the wall of the tank. Thelayers of burlap may be of various forms and depend at their centralportions preferably in the form of an extended V, and in order to holdthem in this shape they are weighted down at their central portions bymeans of strips 13, preferably of iron, said strips being suitablysecured to the burlap.

There is a space 1.4 above the burlap layers and with this space the gaspipe 15 connects, said gas pipebeing secured to the central upperportion of the tank.

The mixed oil and air issuing from the vertical pipes or chamberextensions 7 into the space between the upper surface of oil and theburlap layers is caused to pass through the said burlap layers beforereaching the space I body of oil. in the tank, W ich action isaccelerated by the Vshape oi the burlap layers, causing the moisture tocollect in drops at the apex of the layers to fall therefrom into thebody of oil. The metal strips 13 at the center of the burlap layers holdthe same in propcrform for this action and prevents the air pressurefrom raising the said layers.

It will be noticed iron) Fig. 3 that the layers of burlap are heldseparate from each other and are not arranged as'one mass.

It will be seen from the above that in producing the gas I avoid passingthe air through the entire body of oil as has heretofore been thepractice and instead of this I bring the proper quantity of air intocontact with the limited and proper quantity of the oil, thereby Isecure more uniform results, giving the apparatus a capacity forproducing a greater amount of gas for a longertime and making theapparatus generally more efiicient.

At the top of the tank I prefer to form a dome 16 in which layers orsheets of metal or burlap are arranged vertically at 19 as shown in Fig.l or as indicated at l7, and from this dome the gas pipe extends. Thisdome will act as a condense; to take out moisture and holds. supply ofcomparatively dry gas. The gas chargedair passes into this dome throughthe openings 18.

i arrange battle plates 19 in the domc forming a circuitous path for thecarbureted air therein.

1 do not wish to limit myself to the combination of the dome and theburlap layers at the top of the tank.

I do not wish to limit myself to the burlap as other material may beused.

As shown in Fig; 2 I place bent pipe traps at 20 which will let outthegasoiex'ie from thedome end dlschalrgeit back into the main chamber hile et the sam time they will not allow the air to fiasethiougli theihthe dome. Such a trap can be used with either arrange ment of strainers.I an; awarethat it has been proposed to discharge air throng 1 throughperforations in said pipe andibel o This method is not'deslr able and infact impmcti'cable e. oil- A 19am i, while/W11 ellylmliwmittethwpetttqat xhr andair pipe;
